This may be the dumbest question ever. When I shoot verticals to have my shutter triggering arm up my arm hits my regulator hose. How does one avoid that?

Turn it the other way? If it's really annoying you might need to change hoses (longer or shorter) or add a swivel?
I shoot verticals in both the trigger up and trigger down positions and don't really think this is an issue for me, but now I'm going to pay more attention tomorrow 🤣

I’m intrigued by this. It’s an issue I’ve never noticed- although, I do occasionally find I have to tilt my head slightly to avoid blowing bubbles where they can be unhelpful.

Annoying indeed. Assuming you're right handed, Jeanie, is your reg coming over your right shoulder? Kristin’s idea of adding a swivel is a neat one.

And by my experience, there is no such thing as a dumb question. I’ve heard some dumb answers though…..
